He has made up his mind. He doesnt want to do it, end of story. There aint gonna be a Ghostbusters 3 and if there is, its not going to be with the original cast, or all of them anyway. Leave it alone I say. A few years ago if everybody had agreed then id have went for it, but theres been too much pissing about. We got a part three with the game anyway and it was great.
